in the mid-south I think the flow starts in mid march with hawthorn and is basicly over in late june when the privet is finished. What about other regions?
July 4th here is normal for clover flow bur weather can move it up or down a couple of weeks. Soybean may or may not show up depending again on the whether. Many regions are very different with weather bein the final wild card. You've asked a tough question.
